It is 12.5. I think my answer was deleted by someone wrongly. Notice that the diameter is the *whole* length BD, so 8+a. One can get a, but it is clear that BD is greater than FG, which is 12, so the only answer greater than 12 is 12.5. Now here is the proof, but being *smart* also helps in many cases and should not be deleted. One can form a right triangle with BHF, and another one with FHB. They are similar, so that: 8/6 = 6/a, or a = 36/8=9/2=4.5. Now 8+4.5=12.5 Hope it still helps
